    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    NOx and CO Emissions Of Rice Straw, Coconut Shell and Biobriket

    Biobriquette can be used to anticipate the high fossil fuel needed as alternative fuel, cheap and easily obtained. Biobriquette is solid fuel and derived from organic residues. Generally, coal biobriquette making process used biomass waste such as straws, sawdust or various shell biomasses (coffee, cocoa, hazelnut, corn, cassava and jatropha waste). In this research used biomass waste from rice straw with adding the various coconut shell compositions. The compositions of rice straw: coconut shell are 50% : 50 %, 60%: 40%, 70% : 30%, 80% : 20%, 90% : 10% with 10 % tapioca adhesive addition. One of variables determined the biobriquette quality was pollution level generated in the combustion process which was Nox and CO gas. In this research obtained best quality composition of rice straw : coconut shell was 50% : 50% and had emission level for Nox gas at 3.17 mg/m3 and CO gas at 0.5 mg/m3. The biobriquette product was feasible due to the emission value were below the emission standards set for Nox ≤ 1000 mg/m3 and CO ≤ 500 mg/m3

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

    The Mocaf flour maker that made for this research consists of grater, dryer and discmill. In this research is caried out design of dryer that the type of belt conveyer dryer by using blower as a source of air suply and combining grater and discmill into one series. The performance test of the tool for this research is reviewed from the analysis of HCN and proteint content for the Mocaf flourproduced from Manihot Glaviozii for drying temperature in the dryer with temperature variations 80, 85, 90, 95 and 100 ℃. Based on the performance test of the tool, the drying process using temperature variations in the dryer affects the results of the reduction of HCN and protein content in the Mocaf flour products produced for drying process with the temperature variation showed that the greater the drying temperature, the greater the reduction of HCN and protein contained in Mocaf flour.The results of HCN analysis contained in Mocaf flour products experienced HCN reduction 66% while in the reduction of protein contained in Mocaf flour 67.83
